Enable/Disable Discrete 2 of 5
Parameter # 5
To enable or disable Discrete 2 of 5, scan the appropriate bar code below.
Set Lengths for Discrete 2 of 5
Parameter # 20, 21
The length of a code refers to the number of characters (i.e., human readable characters), including check
digit(s) the code contains. Set lengths for D 2 of 5 to any length, one or two discrete lengths, or lengths within a
specific range. The range for Discrete 2 of 5 lengths is 1 - 55.
•
One Discrete Length - Select this option to decode only D 2 of 5 symbols containing a selected length.
Select the length using the numeric bar codes in Appendix F, Numeric Bar Codes . For example, to
decode only D 2 of 5 symbols with 14 characters, scan D 2 of 5 - One Discrete Length , then scan 1
followed by 4 . To correct an error or to change the selection, scan Cancel on page F-3 .
•
Two Discrete Lengths - Select this option to decode only D 2 of 5 symbols containing either of two
selected lengths. Select lengths using the numeric bar codes in Appendix F, Numeric Bar Codes . For
example, to decode only D 2 of 5 symbols containing either 2 or 14 characters, select D 2 of 5 - Two
Discrete Lengths , then scan 0 , 2 , 1 , and then 4 . To correct an error or to change the selection,
scan Cancel on page F-3 .
•
Length Within Range - Select this option to decode a D 2 of 5 symbol with a specific length
range. Select lengths using numeric bar codes in Appendix F, Numeric Bar Codes . For example, to
decode D 2 of 5 symbols containing between 4 and 12 characters, first scan D 2 of 5 - Length Within
Range . Then scan 0 , 4 , 1, and 2 (enter a leading zero for single digit numbers). To correct an error or
change the selection, scan Cancel on page F-3 .
•
Any Length - Scan this option to decode D 2 of 5 symbols containing any number of characters within
the scanner’s capability.

NOTE
Due to the construction of the D 2 of 5 symbology, it is possible for a scan line covering only a portion of
the code to transmit as a complete scan, yielding less data than is encoded in the bar code. To prevent
this, select specific lengths (
D 2 of 5 - One Discrete Length, Two Discrete Lengths ) for D 2 of 5
applications.
